1.Check how the machinery works
Before starting, the injection molding machine and auxiliary machine must be inspected to ensure that the equipment is in normal condition (according to the requirements of L1 equipment operation records). If any problems are found, the maintenance personnel should be notified in time.
2.Power supply for injection molding machine
Turn on the power supply of the injection molding machine, the mold temperature of the mechanical and electrical source, the general mold temperature is set to 80℃, the drying mechanical and electrical source (raw materials need to be dried at 80℃ for 4 hours), the cold water mechanical and electrical source, the exhaust fan and other power supply, turn on the injection molding machine oil pump motor screw and begin to heat up.
3.Grease is applied to the guide post
Wipe the oil stains on the parting surface, guide post, guide sleeve, slider, cavity and oblique guide post of the die with oiling paper. Apply grease to the surface of guide post, guide sleeve, slider and oblique guide post to prevent the die from wear during long working time.
4.Confirm mold condition
Confirm the mold condition, check whether there is damage, whether the oil circuit is smooth, whether the pipe connection is connected in place, whether there is oil leakage phenomenon.
5.Automatic cleaning key
When the temperature meets the requirements, discharge the material, open the baffle of the feeding port, press the automatic cleaning key of the operation panel of the injection molding machine, and clean the material for 2-3 times. After the completion of the cleaning, clean the remaining material of the nozzle and the mold suction nozzle.
